Another .olo'ectis to provide Aa-,cast metal ralroad'rcrossing rthat is .not only stronger andmore reliable thanaponei-,piece cast metall crossing, but ,it isveasier to Vmanufactureand capable of being produced, at a lowerv cost.

rAnd still another object'of my invention.A

is. to provideV a built-up, vcastmetalY railroad crossing that :iseasy to-assemblelandjwhose component parts are of such design that separatef,. tie plates and-brace'szare not-requiredY to mount? and anchor the,crossing;onthe track.

A To this endI havefdevisedy afrailroadcrosS` ing `,that is composed of a. plurality -oiacast metal members detachably combinedl withi each other iny sucha'way as to produce a:

will be held securely against vertical movement by parts on said extensions which conform to the fishing section of the rails. of the extensions above referred to are of the same construction, and each comprises a wheel tread part 5 of about one-half the width of the top vweb 2 of the member, that extends along one side of the headof Ythe rail, and a depending, vertically-disposed leg 6 on said part that conforms approximately to the fishing section of the rail and laps over the base iange of the rail, as shown in Figure 2. 1f desired, the said depending part 6 can be pro- 'vided with a plurality of ribs 6a, shown in Figures 2 and 6, that are adapted to bear against the underside of one-half of the head of the rail and against the outside face of the web of the rail. By making the extension of less width than themember of which it forms a part, I produce a shoulder on said member against. which the end of the rail abuts, thereby effectively preventing the rail from moving longitudinally in one direction relatively vto the member to which it is attached, and by providing said extension withv a part that projects into and conforms approximately to the fishing section of the rail, I effectively prevent vertical movement of the rail.` VAs shown in Figure 2, the extension above described in provided with a plu-` rality of holes for receiving. bolts 7 that are used to connect the rail to the same, it being preferable to arrange an angle bar or .fish plate 8 on the gauge side of the rail, as shown in broken lines in Figure 2, and have the bolts 7 pass transversely through the outside leg andpart 6 of the extension, through the web of the rail, and through the angle bar 8.

The intermediate members B andthe end members C are shaped so that they can be arranged in abutting relationship with the main members A, with portions of said main mem-l bers disposed so asto prevent the intermediatemembers B and end members C from moving vertically either upwardly or downwardly. This feature of my invention is shown*l more clearly in Figures 4 and 6 of the drawings, wherein it will bernoted that the members B and C are each provided with a vertically-disposed attaching flange 9 that bearsk against the side leg 1 of the member A'and is securely clampedV to said side leg by bolts or other suitable fastening devices 10. v Said attaching flange 9 `is made long enough so as to All Y that they will lap over the adjacent baseflange 4 of the main member A, as shown clearly in Figure 4. Holes l2 are formed in the tie plate portions 1l to receive tie spikes and the members A are provided with horizontallydisposed ribs or lateral projections 13 that lap over the attaching flanges 9, and thus cooperate with the base flanges 4 on the main members A to form pockets for the portions of the intermediate members B and end members U that butt against said main members.

By connecting the co-operating members of the structure together in this manner I produce a crossing-that is strong enough to successfully carry the loads to which it is subjected, but'which is more flexible than the conventional one-piece cast vmetal crossing. Such a crossing can be :manufactured at a relatively low cost, because inexpensive patterns of simple design can be used in the operation of casting the various members from which the crossing is composed and an imperfection or defect'in one member of the tually support each other in such a way as to overcome the necessity of using rail braces.'

The members A, B andY C of the crossing have tie engaging surfaces 'of suflicientarea` to insure a firm bearingfor Vthe crossing on the support on which it rests, and the integral tie plate portions ll Vofthemembers B and C overcome the necessity of using separate tie plates under theintersecting portions of the crossing. i Y 1 vIf desired, the portions Vof the members A, B and C through which the bolts 7 and'l() pass canvbe reinforced and strengthened by integral internal lugs 7a and 10a in which the bolt holes are formed. External lugs 7b and 10b can also be formed on said members so as to form surfaces that co-operate with the heads of the bolts 7 andLlO to prevent the the portions of said main members A to which the intermediate members B and end membersC are attached. Y

Having thus describedmy invention, what I claim as new and-desire to secure by Letters Patent is:

V1. yA .railroad crossing, comprising a pair of main members that l(zo-operate with' the rails of `one track, each ofsaid main mem- 1 bers consisting of a casting of substantially 'inverted channelshape in cross section provided with laterally-projecting base flanges,

' slfintermediate members and end memberscar ranged at an angle vto said main members so c l v asto form'continuatio'ns of the rails of the yother track, integral attaching flanges `on said intermediate and end members thatv bear V against the sides of said main members, tieV plate portions on lsaid intermediate and end members integrally connected to the attaching flanges of same and recessed so as to lap over the base flanges of said main members,

ribs or. projections on'said main members that lap over the top edges of said attaching c flanges, and reduced extensions at the outer A ends of Vsaid main members. and end members .to vvhich the track rails are connected, said v-extensions being constructed so as to prevent relative vertical movement between said eX-` tensions and the track rails.l f A Y 2.
